Outflow — if you see the decreasing water, so you are abandoned by vital forces and luck.
It is a sign of a vital stream and whirlpools, and also a stream and whirlpools of your emotions. Life is the movement. Time to project the emotions outside and time to constrain them. Time of a crop and time of need. Doors are closed and doors are opened. It only changes. And has to be.
Circulation of your emotions.
